I have read about drift problems w/ the FS headtracker units. Not bad mouthing but for the price of the units, I would like them to work the way they are suppose to. ATM FS source is very limited and one of the options I have does have a HT in it - has this problem been rectified or is it still a problem?

Also, can the AttitudeSD HT unit be removed or will there be a version w/ just the Vrx w/ no HT?

FWIW will be using a Futaba 7C & 9C for TX w/ Fasst and FrSky modules if that makes any difference.
